The design is transferred to the photoresist layer by exposure to UV light through a photomask and the unexposed areas are washed off to obtain the main shape. The transparent film is used to create a photo - mask around the design, and 4 silicon wafers are used for spinning.

The microfluidic device is built by gluing a plate of polydimethylsiloxane (PDMS) to a glass slide. In order to produce a PD-MSM plate with microfluidic properties, a polymer mixture with PDms as hardening agent is produced. The mixture is desalted in a desiccator and poured onto the silicon wafers.

The polymer mixture is then cured in the oven at 70 degrees Celsius in the oven for 2 hours and then in a cold water bath for 3 hours.

After curing the polymer, the PDMS is peeled out of the mould and the input and output is punched into the biopsy mould. The final microfluidic device is produced by connecting the plate to the sliding glass by means of a plasma chamber. After the sonication with ethanol and dried nitrogen gas, both the PDMS coating and the glass slide are cleaned.

Fabricating Microdisks for Optical Application Thick Thermal Oxide on Silicon Wafers

A scientist needed to fabricate microdisks for optical application on small diameters silicon with a 5 micron thick oxide layer. But the lab budget was limited.

We have the solution with 50.8mm and 76.2mm thermal oxide coated wafers.

Thermal Oxide to Fabricate Organic Field Effect Transistors (OFET)

OFET geometry is similar to that of a thin film transistor (TFT). It uses thermally grown oxide as a gate dielectric and a thin-film silicon transistor as a gate. The most common use of this geometry in silicon transistors is a geometry similar to that of the thin-film transistor.

Clients have used the following wafer for the OFET research:

100mm N/Ph (100) 1-10 ohm-cm SSP 500um with 300nm of Dry Thermal Oxide

What Silicon Wafer Should I Use for Raman, SEM, and AFM?

A scientists asked our help:

I am looking to buy Si wafers for Raman, SEM, and AFM. I was told to get some with a 300nm oxide layer, single side polished, and I want either 2- or 3-inch diameter. I am having trouble picking which ones to get, and I don't know how to tell if it has an oxide layer and how thick it is. Is this something you can help me with?

UniversityWafer, Quoted and scientist purchased:

2" P(100) 1-10 ohm-cm SSP 280um with 300nm oxide layer
